Solids
[Page 16 of 32]
Solid figures are 3-dimensional or 3D figures that have width,depth and height. They take up space or volume.
Example of solid figures: Sphere, Cube, Cylinder, Cone, Cube, Rectangular Prism.
As you encounter more challenging questions, you will also encounter
more three-dimensional geometric shapes.
Three dimensional objects, or solids, have length, width, and
depth. The most common solids on standardized exams are rectangular
boxes, cubes, and cylinders.
A line segment that connects adjacent vertices of a solid is
an edge.
You may be asked to find the volume of a solid or its surface
area.
For the solids that you're most likely
to see on your exam, you can find the volume by multiplying
the area of one face by the length of the dimension perpendicular
to that face. We'll look at some examples that will help
make this description clear.
Surface Area:
A solid's surface area is the sum of the areas of each
two-dimensional surface.
Now let's see some examples.
